1914, Serial No. 877,982. Divided and this application filedNove'mber 1, 1915. Serial no. 59,078.

To all whom it may concern:

Be it known that I, WVILLIAM S. ELLIo'r, a citizen of the United States, residing at Florence, in thecounty of Hampshire and State of Massachusetts, have invented certain Improvements in Shearing-Out Apparatus, of which the following description, in connection with the accompanymg drawings, is a specificati0n, like reference characters on the drawings indicating like parts in the several figures. 4

This invention relates to apparatus for use in making eyelets or other articles of that type which comprises a metallic blank provided uponcertain portions w1th a coating of celluloid or other plastic compound. In my prior application Serial No. 877 ,982, filed December 18, 1914, of which the presclosed a method of manufacturing such articles in accordance with whichcelluloid or other plastic compound in the form of a sheet molded upon a metallic blank and then the article is completed by being sheared out from the sheet. This method may be carried out withparticular advantage in covering simultaneously a large number of bl n v V In carrying out the method of my invention in the manufacture of eyeletsthere 18 produced a sheet of celluloid in which is embedded the flange of a metallic eyelet blank while the barrel of the blank projects outwardly'from the sheet. .Uponone surface there appears molded in celluloid a circular ring of convex surface which surrounds. an

opening in the sheet while the barrel of the blank and a portion of the under side of the flange appear through an opening in the other. surface. As above intimated it is proposed to inoldthe celluloid sheet upon a number of eyelet blanks'at the same time and the article of manufacture so produced possesses many novel and'useful characteristics. It comprises a sheet of celluloid having molded on one surface a plurality of raised rings arranged in adjacent rows, and

having corresponding rows of: openings in theother surface through which pro ect the 'metallic barrelsof the blanks. of

-' sheet from the projecting shearing surfaces this kind may be readily handled and transported if desired and the eyelets may be completed by being sheared or punched out of the sheet at any convenient time or place.

I have designed novel apparatus for shearrels of the blanks which project from the molded sheet and'having a raised shearing surface disposed concentrically about each hole and extending outside the periphery of the covered eyelet flange, together'with an oppositely disposed shearing plate provided with shearing surfaces shaped to cooperate with those already discussed.

ent application is a division, there is dis- I I Another feature of he invention onsists in ejecting pins arranged, to detach the completed eyelets from the recesses of the shear ing plate, 'and still another feature consists in stripping pins for removing the waste of the holding die plate.

As herein shown the ejecting pins and" 1 shearing die surfaces are formed in a pair of relatively movable plates so that the ejecting pins may be maintained in inoperative position during the shearing operation and' then maybe operated simultaneously to eject the completed eyelets. This construction also constitutes another feature of the invention. These and otherfeatures of the'invention will be best understood and appreciated from the following detailed description of a preing; from the celluloid sheet the completed 1 article and such -apparatus constitutes the ferred form of apparatusselected for 'pur- V poses of illustration and shown in the accompanying drawings, in which,

' Figure 1 is a View in perspective of the shearing-out apparatus; Fig. I 2 is a plan view of part ofthe, holding plate of the shearing apparatus showing a portion of the sheet to be sheared; Fig. 3 is a sectional I view of a part of the shearing-out apparatus with-the parts in their] initial position, and Fig. 4 is a similar view on an enlarged scale of the parts in theposition which they occupy at the conclusion of the shearing operation.

plied to the manufacture of eyelets covered with celluloid but it should be understood that this is for convenience in illustration only and that the apparatus may be employed in the manufacture of other articles, such as lacing hooks, studs, or buttons, which are to be covered with celluloid or any plastic compound.

The holding die member comprises a plate 50 having a number of flanged tubes 56 set therein. The arrangement of these tubes is similar to that of the dies used for holding the eyelet blanks in the molding operation. The tubes, however, are located slightly closer together in order to allow for the contraction of the celluloid sheet when removed from the molding dies. Surrounding each of the tubes 56 are a number of small stripping pins 58 which work freely in the plate 50 and are normally projected by springs 59 arranged in sockets in a plate 52 which underlies the plate 50.

The coiiperating shearing die comprises a plate 60 having formed therein a number of recesses 66 concentrically arranged with respect to the tubes 56. The recesses 66 are of such size as to fit snugly upon the projecting ends of the tubes 56 and to co6perate'with the outer edges thereof in shearing the celluloid about the flange of the eyelets. The plate 60 is rigidly secured by the bolts 72 and distance pins in spaced relation to a plate 64. Maintained between these plates and loose on the distance pins 70 is a third plate 62 in which are set a number of ejecting pins 68 one of which projects into each recess 66. A compression spring 74 ar ranged about each bolt 72 tends normally to move the intermediate plate 62 away from the. shearing plate 60 so that the ejecting pins 68 shall be entirely out of engagement with the celluloid sheet.

In practice the shearing die plates are placed in a press of suitable construction such, for example, as is partially illustrated in Fig. 1. As therein shown the stationary bed plate 54 of the press has standards set therein which carry yoke pieces 63. The reciprocatory head 84 of the press has secured to it the plate 64 which carries the shearing plate 60 and the ejecting plate 62, as already explained. The ejecting plate 62 projects at its ends beneath the yoke pieces 63 which are so disposed. that during the upward movement of the head 84 they encounter the ends of the plate 62 and move it downwardly with respect to the shearing plate 60 against the compression of the spring 74. In this manner the ejecting pins 68 are projected through the opening 66 and eject the completed eyelets which are retained by friction in these openings after the shearing operation. The head 84 comes to rest with the ejecting plate in its lowermost position as clearly shown in Fig. 3.

In carrying out the shearing operation the molded celluloid plate shown in Fig. 2 is placed upon the holding die plate 50 with the eyelet barrels projecting into the openings in the tubes 56 and the molded eyelet flanges supported out to the point at which the shearing is to take place by the flanges of the tubes 56. The press is then started and the head 84 descends. As soon as the ejecting plate 62 is moved out of engagement with the yoke pieces 63 the ejecting pins 68 aremoved upwardly into inoperative positions as shown in Fig. 4 and in the continued downward movement of the shearing plate 60 the shearing edges of the recesses 66 cooperate with the shearing edges of the tubes 56 and shear each eyelet from the sheet 30. The head 84 is then elevated and the completed eyelets ejected. In the shearing operation the celluloid sheet 30 is forced downwardly upon the flanged ends of the tubes 56, as shown in Fig. 4, and when the head 84 is elevated the stripping pins 58 lift the perforated sheet off the ends of the tubes.

Having thus described my invention, I claim as new and desire to secure by Letters Patent of the United States:
